    Aplicación de mucílago de cacao para el control del musgo (Rigodium implexum) en el cultivo de café robusta (Coffea canephora)

    To evaluate the effect of different concentrations of fermented cocoa mucilage on the control of Rigodium implexum in robusta coffee plants (Coffea canephora), as an agroecological alternative for the management of this organism. Methodology: The research was carried out at the Sacha Wiwa Experimental Center, La Maná canton, Cotopaxi province, Ecuador, using a randomized complete block design with five treatments (100, 75, 50, and 25% fermented mucilage, plus a control), four replications, and 60 experimental plants. The physicochemical properties of the mucilage were characterized, and the mortality percentage, moss coverage, and foliar phytotoxicity were evaluated at 15 and 30 days after application. Data were analyzed using ANOVA and Tukey's test (p≤0.05). Results: The mucilage presented a pH of 5.04, 0.12% acetic acid, and an alcohol content of 0.12%. In the second evaluation, the 100% and 75% concentrations achieved 100% and 88% mortality and reduced moss coverage to 0% and 12%, respectively, without showing foliar phytotoxicity. Conclusions: The 100% and 75% concentrations showed higher efficacy for controlling R. implexum and represented a viable agroecological alternative with potential application for moss management in robusta coffee plantations. Further studies on dosage, application frequency, and treatment behavior under different agroecological conditions were considered pertinent.
